Which 1998 Russian government action preceded a major global hedge-fund market crisis?

Russia’s debt default preceded the major global hedge-fund crisis involving Long-Term Capital Management in 1998.

On August 17, 1998, Russia devalued the ruble, declared a moratorium on some foreign debt payments, and restructured domestic government debt. The announcement shocked investors who had treated Russian government securities as relatively attractive instruments.

The resulting flight from risk damaged markets far beyond Russia. Long-Term Capital Management, a highly leveraged hedge fund whose positions depended on relationships among bond prices and other assets, suffered enormous losses. The Federal Reserve Bank of New York helped arrange a private-sector recapitalization to prevent an uncontrolled collapse.

The rescue was not a government bailout funded directly by U.S. taxpayers, and the Federal Reserve did not take ownership of the fund. The episode demonstrated how leverage and interconnected trading positions could transmit stress across international markets.
